5.1.3 Viscosity
Switching delays may occur in the case of highly viscous liquids. Make sure that the liquid can
easily run off the tuning fork:
• If installing in vessels with high-viscosity liquids (A), the tuning fork may not be located in
the installation socket!
• If installing in vessels with low-viscosity liquids (B), the tuning fork may be located in the
installation socket!
• The installation nozzle must be no less than the minimum diameter of 50 mm (2.0 in).

5.1.4 Buildup
Make sure that the installation socket does not exceed a certain length so that the tuning fork
can project freely into the vessel.
Possibilities for optimization:
• A vertical orientation of the point level switch keeps buildup to a minimum.
• Preferably flush-mounted on vessels or in pipes.

 6 Buildup on tank wall, pipe wall and tuning fork
5.1.5 Weld-in adapter with leakage hole
If installed horizontally, make sure that the leakage hole is pointing down. This allows leaks
to be detected as quickly as possible.

5.1.6 Marking
The marking indicates the position of the tuning fork. If installed horizontally in vessels, the
marking is face up.
The marking appears either as a material specification (e.g. 316L) or a thread designation

• On the hexagonal bolt of the process adapter
• On the nameplate

liquid can drip off.
The electrical connection, e.g. M12 connector, should be pointing down with the cable. This
can prevent moisture from penetrating.

6 Electrical connection
6.1 Connection conditions
The measuring device has two modes of operation:
• Maximum point level detection (MAX): e. g. for overfill prevention
The device keeps the electrical switch closed as long as the sensor is not yet covered by
liquid or the measured value is within the process window.
• Minimum point level detection (MIN): e. g. to protect pumps from dry running
The device keeps the electrical switch closed as long as the sensor is covered by liquid or the
measured value is outside the process window.
Choosing the "MAX" / "MIN" mode of operation ensures that the device switches in a safety-
oriented manner even in an alarm condition, e. g. if the power supply line is disconnected. The
electronic switch opens if the point level is reached, if a fault occurs or if the power fails
(quiescent current principle).
• IO-Link: Communication on pin 4; switch mode on pin 2.
• SIO mode: If there is no communication, the device switches to the SIO mode =
standard IO mode.
The functions configured in the factory for the MAX and MIN modes can be changed via
IO-Link:
• HNO/HNC hysteresis
• FNO/FNC window
6.2 Supply voltage
SIO mode
10 to 30 VDC
IO-Link mode
18 to 30 VDC
IO-Link communication is guaranteed only if the supply voltage is at least 18 V.
